GeForce GTX 570 vs Radeon HD 6750 1GB

Intro

Compare those specs to the Radeon HD 6750 1GB, which features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Radeon HD 6750 1GB		86 Watts
GeForce GTX 570		219 Watts
	Difference: 133 Watts (155%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 570 should in theory be quite a bit better than the Radeon HD 6750 1GB overall. (explain)

GeForce GTX 570		152000 MB/sec
Radeon HD 6750 1GB		64000 MB/sec
	Difference: 88000 (138%)

Texel Rate

The GeForce GTX 570 is quite a bit (about 68%) more effective at texture filtering than the Radeon HD 6750 1GB. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 17820 (68%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is the winner, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 17680 (152%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
